Ok just an update on this as i am still getting the same problem. Just fitted a brand new series 2 PTU, coolant temp sensor and found a fuel leak on the top of the plenum but it is still taking agaes to start and thus killing the battery before it has chance to start. I have some braided fuel hoses on the way which will eliminate any fuel leaks from the top side but how many fuel hoses are there under the plenum that could be leaking? I had a look under there when it was running and i couldnt see any leaks.

 

I changed my fuel filter about 6k miles ago however the car has always started slow so i just wanted to confirm its not possible to install the fuel filter the wrong way round is it as i put the new one in the same way as the old one came off.

 

Another thought is i have HKS spark plugs fitted and ive read a few posts about recommended spark plugs and thought this could have something to do with it but these were also changed 6k miles ago.

 

Any more ideas will be great help as when she is warm will start without any problem really its just mainly from cold after sitting for the night or so.

 

Thanks for the help

mine had a fuel leak on the injector pipes under the plenum but u could only see it when turning the engine over..it wasnt visable when started or when off!! had to take the plenum off & remove the injector rail * used liquid metal to fix it??

Is that the rubber hose at the front of the plenum? ive sorted the leak i had at the damper and down to the fuel rail. Im sure its gotta be fuel problem i will have a look with someone turning it over today.

no the metal pipes that loop around the metal had a hair line crack!

The fuel system does have a non return in the fuel tank.to check its working undo a fuel pipe ten minutes after a run.If you have pressure its doing its job.

right had a good crack at this tonight and found a smell of fuel around the pressure regulator so had the small top hose off and the one that goes down to the rail and changed both of these as that is the only place i could smell fuel coming from so surely that has done it will see tomorrow morning when i start from cold again.

 

Series 2 PTU arrived from CZP yesterday as well so got that fitted on there.

 

Also swapped out all my old boost hoses for new blue silicone ones looks a damn sight better now and should eliminate any boost leaks :)

Had a go at starting this morning however was still a bit slow took about 10 seconds to start im sure there is still a problem there :(

Nope problem is still there after sorting a fuel leak and a new series 2 PTU have some NGK spark plugs on the way as that may be a cause what does everyone else reckon?

clean all the connectors u can see (injectors/coil packs/temp/tps/idle/cas) they go green very easy & it dont cost a penny to clean them

Finally i may have cured the fault started first time earlier in less than 5 seconds and again when i went back later on. Gonna try again in the morning for the final test. Changed my spark from the HKS ones i had in to NGK PFR6B-11B spark plugs and the fault may have gone. I replaced the spark plugs about 10 months ago for the HKS ones as there was already HKS ones when i bought the car just over a year ago. Result :sorcerer: thanks for the help everyone :)

Fault is still there :( however was over a zedworld for a conzult and try to get to the bottom of this fault and confirmed that the engine is really low on compression and ive got a leaky injector. Will have to get my spare engine stripped and rebuilt to put that in so that i can use my current engine as my spare to rebuild with uprated internals. In a way im kinda happy that i know what is going on in my engine now but even more happy that i got a spare engine that needs head gaskets for 132 quid the othe week.

 

Thanks for all the help again and ill start a thread to make sure i get everything changed on my spare engine that i need to.
